Abstract: A stability meter comprises a translational accelerometer (1) which has a working axis along which it is sensitive to gravity. It is mounted on a vessel with the working axis horizontal when the vessel is in the upright position such that it transmits signals proportional to the sine of the angle of roll of the vessel to microprocessor based apparatus (2). The microprocessor (12) conducts a Fast Fourier Transform on a plurality of samples from the accelerometer (1) in order to determine the dominant rolling frequency. The apparatus (2) comprises a display (8), a printer (9), a keyboard (10), a clock (14) and memory unit (16). The dominant rolling frequency is used to calculate the transverse metacentric height of the vessel. The value of the transverse metacentric height is transmitted to the display (8) as a measure of the stability of the vessel.

Title: Process for producing alkyl group-substituted aromatic hydrocarbons
IPC: C07C15/02
Filed: 1987-11-10
Granted: 1992-09-02
Abstract: This improved process for producing alkyl group-substd. aromatic hydrocarbons comprises reacting an aromatic hydrocarbon (1) with an alkylating agent (2) in the presence of a mordenite zeolite catalyst treated with a fluorine-contg. cpd. The alkylating agent (2) is selected from olefins, aliphatic lower alcohols, and alkyl halides (pref. propylene). The pref. aromatic hydrocarbon (1) is biphenyl, dibiphenyl or naphthalene. The typical product is p,p'-diisopropylbiphenyl. The fluorine-contg. cpds. can be hydrogen fluoride, ammonium fluoride, CF3Cl, SF6. As an example, 4,4'-dihydroxybiphenyl is produced by the acid-decomposition of 4,4'-diisopropyl biphenyldihydroperoxide which is obtd. by oxidising 4,4'-diisopropylbiphenyl with oxygen molecules. The above 4,4'-diisopropylbiphenyl is reacted with acylising agent to obtain 4,4'-diacyloxybiphenyl.

Abstract: When a competitor or a group of competitors passes the finishing line, a video camera (6), two time generators (8), a video recorder (9) and a display in the form of a monitor (11) and/or of a video picture printer (12), and a light barrier are able to produce, in a very inexpensive way, finishing-line pictures with at least two times faded in, namely the true finishing time of a first competitor triggered by the light barrier and the precise time which has elapsed from the start at the time said picture was taken. From the time difference, distance sections each corresponding to one hundredth of a second can be determined from which the finishing times of the runners arriving immediately after the winner can be exactly established. In practice one finishing-line picture is sufficient to be able to measure precisely to one hundredth of a second the finishing times of runners arriving almost simultaneously with the winner. Competitors arriving after a fairly large interval can in turn obtain their exact finishing time by means of the light barrier in a further still picture.

Abstract: A polishing pad material is provided with a cellular polymeric layer containing elongated cells normal to the major surfaces of the material, such that the cell openings on the polishing surface of the material comprise a majority of the surface area, and the cells have a mean diameter of about 50 to 200 microns with the diameter of the surface openings being preferably larger than the cell diameters below the surface. The cells are preferably cone-shaped and have a depth at least 1.5 times the diameter of the surface openings. The pad material is formed from a poromeric material, preferably polyurethane elastomer, with microporous cell walls having pore diameters less than 0.1 times the diameter of the cells. The polishing pad material may be made according to conventional poromeric technology, but instead of removing the usual top poromeric skin, the poromeric layer is inverted and the original bottom poromeric skin and any attached substrate are removed to open and expose the cells at a plane corresponding to their largest diameters.

Granted: 1993-09-15
Abstract: For the overheating protection or overload protection of, in particular, ballast units, a connecting terminal has a base body in which at least one terminal insert (2') with two connecting contact points (3') is provided, which contact points are electrically insulated from one another. Their conductive connection is achieved by means of a current- or temperature-sensitive protecting element (5) which is arranged in a retaining chamber (4, 4'), offset from the terminal inserts, and is connected to the two connecting contact points (3'). These contact points are constructed on two individual terminal bodies (12), each of which has a screw terminal for the conductor which is to be connected or the contact tongue of the ballast unit and a connecting contact element, designed as a crimped terminal or terminal clip for one contact end of the protecting element. The walls (6) of the retaining chamber (4) also provide air and leakage paths which are also adequate for transformers with relatively stringent safety requirements. <IMAGE>

Abstract: A multilayer structure comprising (C) a substrate layer, (A) a surface layer of a thermoplastic resin, and (B) an intermediate layer of a thermoplastic resin sandwiched between the (C) substrate layer and the (A) surface layer, wherein the (B) intermediate layer contains 0 to 70 % by weight of a flake inorganic filler, the peeling strength between the (A) surface layer and the (B) intermediate layer is from 0.3 to 2.0 kg/15mm, and the peeling strength between the (B) intermediate layer and the (C) substrate layer is at least 1.2 times as large as the peeling strength between the (A) surface layer and the (B) intermediate layer. When a packaging container is produced by forming the multilayer structure into a container body and sealing the container body with a lid, easy openability and high sealing property will be ensured because the opening of the packaging container is not operated by using the delamination between the sealed portion but by using the easy delamination between the surface layer (A) and the intermediate layer (B). The use of the multilayer structure for production of packages is economically advantageous because the recovered scrap can be reused as the material for the substrate layer (C) without affecting the peelability of the surface layer (A).

Title: Surveying of boreholes

Filed: 1989-05-30
Granted: 1993-03-03
Abstract: A method of deriving the true magnitude of the terrestial magnetic field in the direction of the longitudinal axis of a borehole at a region of the borehole occupied by an instrumentation package equipped with magnetic vector measuring means for measuring the lateral magnetic vectors Bx and By and further equipped with gravitational vector measuring means for measuring each of the three gravitational vectors Gx, Gy, and GZ. The method comprises the steps of performing said measurements of the magnetic vectors and the gravitational vectors and from said vector measurements solving the equation:-  Bze = (BVe.Ge - Bx.Gx - By.Gy) / Gz where BVe is the vertical component of the terrestial magnetic field at the location of the borehole, and Ge is the terrestial gravity field. The terrestial gravity field Ge may be derived as the square root of the sum of the individual squares of the individual gravity vectors Gx, Gy and Gz, according to the equation:-  Ge = (Gx<2> + Gy<2> + Gz<2>) <1/2 > . The invention is based on the assumption that the vector measurements, and in particular the lateral magnetic vectors, are substantially uncorrupted by the drillstring or the bottom-hole assembly.

Abstract: A TTl output driver gate configuration which has reduced voltage spikes on internal power supply potential and ground potential nodes includes a P-channel pull-up transistor (P1), an N-channel pull-down transistor (N1), a NAND logic gate (14), a NOR logic gate (16), a first positive feedback amplifier circuit (18), and a second positive feedback amplifier circuit (20). The pull-up transistor (P1) and the pull-down transistor (N1) have gates which are made serpentine. The reduction of voltage spikes is achieved by slowing down the turn-on times of the pull-up and pull-down transistors during transitions due to the distributed resistances and capacitances of the polysilicon material used to form the serpentine gates thereof. The first and second positive feedback amplifier circuits (18, 20) are used to pull the undriven gate ends of the respective transistors all the way to negative and positive supply potentials so as to facilitate transitions at an output node.
